Oestra® for Endometriosis

Oestra® is formulated to boost DHP metabolite production in uterus, which calms inflammation, stops heavy bleeding, reduces pain and rebalance hormones at the root of endometriosis symptoms. Start anytime during your cycle and take daily. You can stop Oestra® every 28 days to have a period, or choose to skip periods. Track your progress monthly to see the difference

Getting started

How Oestra® is different

Oestra® is a plant-based hormone therapy that offers a non-surgical, non-birth control option for endometriosis by targeting the root causes: inflammation and hormonal imbalance.

Reduces pain & inflammation: Oestra® is designed to reduce pain during your period, sex, and exercise, as well as reduce heavy bleeding.
Bioidentical, not synthetic: Unlike hormonal contraceptives, Oestra® uses plant-based, bioidentical estradiol and micronized progesterone to stabilize hormones without the side effects of birth control.
Smarter delivery: The vaginal application bypasses the liver, allowing for higher absorption and more stable hormone levels.

Why vaginal delivery is a smart choice

Oestra® is a cream applied vaginally, which allows it to be absorbed directly into the bloodstream. This method bypasses the gut and liver, helping your hormones get where they’re needed faster and more effectively.
Systemic and highly bioavailable • Vaginal delivery bypasses liver metabolism, allowing nearly full absorption of estradiol and progesterone—far better than oral (10-20%) or topical (3-20%). This leads to more stable hormone levels and better symptom control.

More effective, fewer side effects • It delivers consistent results with fewer fluctuations and side effects. Hormone levels remain steady, improving your comfort and results. Clinical evidence—including 100+ studies—supports its effectiveness.
Proven safety • Vaginal hormones don’t raise clotting risks or estrone levels, and they protect the uterine lining. Multiple clinical trials show
controlled absorption and a strong safety profile compared to oral forms.
Endometrial protection • Vaginal progesterone uses the “first uterine pass effect” to deliver high local levels directly to the uterus, maximizing protection and turn over of the lining, while reducing risks tied to oral forms.
Clinically validated • Multiple randomized trials confirm that vaginal estradiol and progesterone are safe, effective, and superior for
predictable hormone delivery and endometrial health.

How to use

How to apply:
Apply vaginally once daily, in AM or PM. One pump is the measured amount. Do not use any other amount.

Push down once on the top of the bottle until cream dispenses one pearl-sized dose. Shake the bottle if the cream doesn’t dispense after the first few pumps. This is to remove any potential air pockets.
Use your finger to apply to vaginal tissue, in the opening or underside of the labia (the mucosal tissue, not the skin).
Use and store at room temperature. Keep out of reach of children and pets. Dispose of in the trash when empty or expired.
If you miss a dose, resume when you remember. Missed doses can result in a withdrawal bleed.
Stop on day 27 of your 28-day cycle to have a period (if you have a uterus and want to mimic your natural rhythm). Do not use while bleeding. You can resume again once bleeding has stopped, or once 2 days have passed and there is little to no bleeding.
Contact our care team if you don’t want to have a monthly period.
One pump lasts ~24 hours.

How Oestra® works

Oestra® enriches your existing hormone levels rather than replacing them. This helps regulate menstrual cycles, improve sleep and mood, and support energy levels through a fluctuating hormonal landscape.
It is absorbed through the vaginal lining and goes into your bloodstream systemically.

It bypasses liver metabolism to lower the chance of making unwanted liver byproducts.
It keeps hormone levels steady and reliable.
It works throughout your whole body – not just the vaginal area.

Storage instructions

Store Oestra® at room temperature. Avoid heat or direct sunlight. Always secure the cap to maintain product integrity.

Oestra® ingredients

Third-party tested for potency, purity & quality.

Understanding labs

You don’t need labs to start or monitor Oestra® but some women find them helpful to track progress or fine-tune treatment.

Important: Skip Oestra® for 24-48 hours before testing. This gives you a “steady state” reading instead of a temporary peak right after application. *Wait 2-3 months before getting labs.

Helpful labs:

Progesterone

Testosterone

Estradiol

FSH

Target levels for 1 pump/day:

Estradiol: 100-300 pg/mL
Testosterone: 10-30 ng/dL
Progesterone: 2.0-6.0 ng/mL
FSH: 1.0-8.0

What to mindful of

Its purpose: To treat over 100 symptoms of low estrogen, progesterone and testosterone, such as:

Heavy and/or painful periods, anxiety, depression, irritability, insomnia, vaginal dryness, low libido, hair loss, dry skin, dry mouth, dry eyes, fatigue, brain fog, joint and muscle pain, and more

Symptoms of endometriosis, postpartum, PCOS, perimenopause and menopause++

Drug interactions:

If you take any mental health medications, mood changes may happen at first but tend to level out. You may need extra monitoring or support, contact us if needed.
If you’re on thyroid medicine or have low thyroid (hypothyroidism), you may need extra monitoring or support, contact us if needed.
Stop using hormone herbs or detoxers like black cohosh, chaste berry or DIM.
Rifampin, phenobarbital, carbamazepine, and St. John’s Wort can reduce the hormone’s efficacy.
Keto/itraconazole, clarithromycin, ritonavir, and grapefruit juice can slow how your body processes Oestra®.
If you’re taking warfarin, you may need extra INR blood tests.
